Predicted to enable ubiquitin conjugating enzyme activity and ubiquitin protein ligase binding activity. Predicted to be involved in cellular protein metabolic process and negative regulation of retrograde protein transport, ER to cytosol. Predicted to act upstream of or within regulation of tumor necrosis factor production and spermatid development. Predicted to be integral component of membrane. Predicted to be active in nucleus. Orthologous to human UBE2J1 (ubiquitin conjugating enzyme E2 J1). [provided by Alliance of Genome Resources, Apr 2022]
